SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 445,184, dated January27, 1891.

Application filed June 10,1889. Serial No. 313,653. (No model.)

To all whom it may concern.-

Be it known that I, HEINRICH KOEPP, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and usefulImprovements in Sad-Irons; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enableothers skilled in the art to which it pertains to make and use the same,

to reference being had to the accompanying drawings, and to the lettersof reference marked thereon, which form a part of this specification.

My invention relates to hollow 0r chambered sad-irons. Its main objectis to secure a more perfectdistribution and regulation of the draft; andit consists, essentially, of cer tain peculiarities of construction andarrangement, hereinafter particularly described, and

pointed outin the claims.

In the accompanying drawings like letters designate the same parts inthe several figures.

Figure l is a perspective view of my improved sad-iron. Fig. 2 is a planView of the same with thelid or cover partially open and the handleremoved. Fig. 3 is a medial longitudinally vertical section of the iron,and Fig. 4: is a vertical crosssection of the same.

0 F represents the body of the sad iron formed in the usual manner withan interior fire box or chamber for the reception of the fuel by whichthe iron is heated. It is pro vided in each side nearthe bottom withdraftopenings, preferably in the shape of round perforations a (4,arranged up and down in oblique or inclined lines. It is also providedin each of the inclined walls forming the point of the iron with likedraft-openings or perforations a a similarly arranged.

3 is the cover or lid, of the usual form and construction, provided witha handle C of suitable form and material. It is pivoted to the rear endof the body A of the iron by 5 means of a pin or screw I), so as toswing in opening or closing horizontally to eitherside. In a post aformed at the apex of the iron is pivoted a gravitating latch E, and onthe upper side of the lid, near its apex, are formed one or morevertical flanges c e, notched at the center so as to receive and engagethe gravitating latch E, and inclined or beveled from the notches at thecenter toward the op posite edges of the cover, so as to pass in closingthe lid in either direction underneath the latch and automatically raisethe same over the higher portions of said flanges adjacent to thenotches therein. By thus arranging the lid to swing horizontally inopening and closing and by attaching the handle of 6c the iron to saidlid the liability is avoided of accidentallyupsetting the iron andspilling its contents by grasping the handle and lifting it when the lidis unfastened. At the same time the handle serves as a convenient andever-present means of manipulating the lid when it is hot. The manner ofhinging the latch E to the iron and the formation of the notch or recessin the cover with which the latch is to engage may be variously lnodi-7o F F are dampers, consisting each of a side plate perforated tocorrespond with the perforations a a in the sides of the iron, to theinner sides of which they are held by means of rivets or screwsff,secured in the upper portion of each dam perand projectingthroughhorizontal slots in the adjacent walls of the iron, as clearly shown inFigs. 1 and 4, and of a plate F, hinged to the front end of said sideplate, as shown in Figs. 2 and 3, so as to shut snugly against the innerside of the adjacent inclined wall when the damper is closed. Thesedamper-plates are provided with perforations'corresponding with those inthe adjacentwalls of the iron and with inclined or obliqueinwardly-projecting wings ff, located between the oblique rows ofperforations and similar but thinner inclined wings f f extending midwayacross said perfora- 9o tions,'as shown in Fig. I). These inclined wingsnot only serve to hold the fuel away from the openings and therebyaiford a freer and more certain draft, but they serve also to conductthe ashes dropping thereon along 5 their upper inclined faces past theopenings to the bottom of the iron, and therebyprevent their escapingthrough the draft-open ings and smutting the work. The hinged plates F Fare guided and held in place relatively to the adjacent sides of theiron by studs f f projecting upwardly from the bottom of the iron.

By constructing the iron, as hereinbefore described, with perforationsin the inclined walls forming the point or apex and providing the damperwith the hinged plates F, the draft is more perfectly regulated andcontrol1ed,inasmuch as without the perforations or draft-openings in theinclined walls at the front end of the iron the fuel in that portion ofthe iron would not burn as rapidly, and consequently that part of theiron would not be heated to the same degree as the rest of the iron, andif such draft-openings were provided with no means of closing the samethe point of the iron would be liable to become overheated.

Upon the screws or pins ff outside of the iron are pivoted gravitatingplates G G,forn1ed with horizontal slots g, in the extremities of whichare upward offsets adapted to engage with pins g, projecting from'thesides of the iron,so as to hold the dampers either open or closed,thereby preventing their displacement by any movement of the ironincident to its operation. I provide these plates G at their free endswith ontwardly-projecting thumbpieces as shown in Figs. 1 and 2, tofacilitate the shifting of the dampers. The iron is provided at thebottom of the rear end in the usual manner with an opening and door Dfor the purpose of removing the ashes therefrom. The bottom is alsoextended at the rear end beyond said opening and formed with an upturnedflange (Z to prevent the ashes escaping from the adjacent opening fromfalling upon the work.

I do not claim, broadly, as my invention a hollow sad-iron having itssides provided with draft-openings in combination with dampers for theopenings having'a series of inwardlyextending ribs.

I claim 1. The combination, with a chambered sadiron the sides of whichare bent toward each other to form the point and are provided withdraft-openings both in front of and behind the bends therein, of damperscomposed of sections jointed together adjacent to the bends inthe sidesof the iron and movable lengthwise thereof so as to open and close saidopenings, substantially as and for the purposes setforth.

2. The combination, in a chambered sadiron having draft-openings in thesides, of dampers having corresponding openings and inwardiy-projectingwings across'said openings, substantially as and for the purposes setforth.

3. The combination, in a chambered sadiron, of draft-openings formed in'the sides thereof and horizontallymovable dampers provided withcorresponding openings and with inwardly-projecting inclined wingslocated between the rows of openings therein and s milar wings extendingmidway across said openings, substantially as and for the purposes setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
